Integrated Computer Services Pty Ltd v Digital Equipment Corp (Aust) Pty Ltd

Integrated Computer Services Pty Ltd (ICS) and Digital Equipment Corporation (Australia) Pty Ltd (DEC) were parties to a dispute concerning the termination of a software development agreement. ICS had developed software for DEC, and the agreement stipulated that upon termination, DEC would pay ICS a sum calculated by reference to the value of the work performed. ICS alleged that DEC had wrongfully repudiated the agreement, entitling ICS to damages. The matter proceeded to the Supreme Court of New South Wales, Court of Appeal.

The central legal issue before the Court of Appeal was whether DEC's actions constituted a repudiation of the software development agreement, thereby entitling ICS to terminate the contract and claim damages for breach. Specifically, the court had to determine if DEC's conduct, in relation to its obligations under the agreement, evinced an intention no longer to be bound by its terms, or to be bound only in a way inconsistent with the contract's essential obligations.

The Court of Appeal, in its reasoning, applied the principles of contract law concerning repudiation. It held that repudiation occurs when a party demonstrates an intention to abandon or be bound by the contract in a manner substantially inconsistent with its obligations. The court examined the specific conduct of DEC and concluded that it did not amount to a repudiation of the agreement. The court found that DEC's actions, while perhaps causing inconvenience to ICS, did not evince a complete refusal to perform its essential contractual obligations or an intention to depart from the contract in a fundamental way. Consequently, the court found that ICS was not entitled to terminate the contract on the grounds of repudiation.

The Court of Appeal allowed DEC's appeal, setting aside the earlier judgment in favour of ICS. The court ordered that ICS take nothing by its writ.
